Why do people get goose bumps? Why don't fish and dolphins sleep? Why do ships and planes disappear in the Bermuda Triangle? How does camera film record pictures? What are you wondering about? Chances are, Kathy Wollard can find the answers. All the queries in this book of questions and answers were asked by real kids, who mailed and e-mailed them to Wollard's newspaper column, "How Come?" Organized into four loose categories, entitled "Turbulent Earth" (about deserts, oceans, icebergs, fog, volcanoes... anything to do with Earth), "Safari" (about animals), "Bodyworks" (about people), and "Factory Field Trip" (about things we make, such as bubble gum and diamonds), this original science reference book explains 125 mysteries of Planet Earth.
